Frequently Asked Questions

One of our most asked questions is "Which LED aquarium light should I get?" See this comprehensive guide to get our recommendations for each tank size.

It is normal for plants to "melt" when they change environment. There are a few causes for this, one would be different water parameters. It is likely your water is different from ours and the plant will want to restructure and get it's roots in place to start taking in nutrients. This lag time can cause the plant to consume itself to keep itself alive during the transition. (For more details, read our article on crypt melt.)

Another cause would be a plant converting from emersed (grown out of water) to submerged (growing under water). This happen because the plant farms grow the plants above water in very humid environments. When we get them we start growing them under water. Depending on how long the plant has been in our care will be how much the plant has converted. The plants will always end up finishing this conversion in your home aquarium and would be considered normal. 

A lack of sufficient nutrients can also cause plant leaves to start withering away. Make sure you're fertilizing your plants. We recommend using Easy Root Tabs as well as Easy Green Liquid Fertilizer. Without fertilizers, plants will oftentimes die back. For more information, read our article on plant nutrient deficiencies.

Lastly, there is a problem called Anubias rot. This is when the rhizome of an Anubias becomes mushy. This can happen when an Anubias is planted too deeply in substrate and it causes it to rot. This can sometimes be fixed by planting it properly on wood or rock. Then there is another case where the plant may have become damaged and the rot sets in and will consume the entire plant. This can happen at the farm, in our care, during transit, during planting etc. With no specific cause or who is to blame, we offer a refund or a reship of Anubias where this happens when it's been planted correctly and pictures have been provided.

Having products available when you want to order them is our number one priority. We work tirelessly with our vendors to keep all the products we offer in-stock. Unfortunately, disruptions in the supply chain occur and impact our ability to keep certain items in-stock. When an item is out-of-stock, customers naturally want to know when it will be available for purchase again and reach out Aquarium Co-Op Customer Service. Providing estimated restock dates are not possible for Aquarium Co-Op as many times the vendors themselves are unaware of when items will become available again, or we are given vague guesses. This is further exaggerated with live aquarium plants with growth rates susceptible to many natural conditions.

Our advice is to follow us on social media, as we’ll usually announce items become available again, or periodically check in on our website. We don’t want to set an expected date of arrival and miss it. The last thing we want to do is cause an interruption in your plans.

Yes, Aquarium Co-Op's Easy Green liquid fertilizer is completely safe for all fish, shrimp, snails, and other invertebrates. Follow the directions and dose your aquarium with Easy Green up to 20 ppm (parts per million) nitrate to give your plants the essential nutrients they need to thrive.

If you just purchased some new fish, we recommend using a trio of quarantine medications to treat any bacterial, fungal or parasitic diseases they may have. This is the same three broad-spectrum medicines that we use on all fish that enter the Aquarium Co-Op retail store. These medicines can all be used at the same time and are completely safe for all freshwater fish, shrimp, snails, and other invertebrates. Follow these dosing instructions:

  1. If you are treating new fish, make sure the quarantine tank is far away from your normal display tank, and do not let the tanks share any nets, siphons, buckets, or other equipment. Since droplets of water can travel on your hands to another aquarium, make sure to thoroughly wash your hands and arms with soap and hot water between tanks.
  2. If you are treating the entire display aquarium, do a thorough cleaning of the tank to make sure the fish’s environment is optimal and free of any stress factors before starting treatment. Wipe the aquarium walls so that you can easily observe the fish’s condition, clean out the waste in your filter, and use a siphon to vacuum the substrate and change the water.
  3. Remove any chemical filtration (such as activated carbon or Purigen), and turn off any UV sterilizers you may be using. Consider adding extra surface agitation (such as with a simple air stone and air pump), since some medications can change the water’s viscosity and hamper with the fish’s breathing ability.
  4. Do not dose according to the box instructions. Instead, add 1 packet of Maracyn, 1 packet of ParaCleanse, and 1 U.S. teaspoon of Ich-X for every 10 gallons of aquarium water. (Ich-X does not stain aquarium decorations in our experience, but be careful not to spill it because it can stain your skin or clothing.) 
  5. Let the fish soak in the medication, and do not feed them or change any water for 1 week. (If you feel you must feed your fish, wait until Day 4 or 5, and then only feed them very lightly.) You should keep the aquarium filter and heater on during this time. Also, aquarium lighting will not deactivate the medication.
  6. After 1 week has passed, change out 30% of the water in the aquarium. Resume feeding the fish, keep the water quality high, and watch for any change in symptoms.

If you have very weak fish, it may be easier on their bodies to space out the treatment. Bacterial infections are the most common, so use Maracyn first for a week (at the dosage recommended in Step 4). Ich and external parasites are the second most common, so next treat the fish with Ich-X for a week. Internal worms and gill flukes are slower-acting pathogens, so dose ParaCleanse in the third week.

If you can clearly identify the illness that your fish has, only use the specific medication for that disease and following the dosing instructions on the package. Maracyn treats bacterial infections, Ich-X treats fungal infections and some external parasites, and ParaCleanse treats internal and some external parasites.
